Filed: 1961-12-14
Abstract: An alcohol or a mixture of alcohols containing at least 2 carbon atoms is prepared by contacting an aluminium trialkyl in which each alkyl radical contains at least 2 carbon atoms with an oxygen-containing gas, in which the oxygen partial pressure is in the range from 1 to 10 p.s.i.a., in a first stage so that only 2 of the aluminium-carbon bonds are oxidized; contacting in a second stage the product from the first stage with an oxygen-containing gas in which the oxygen partial pressure is higher than that in the first stage and is in the range from 5 to 75 p.s.i.a., the temperature in each stage being from -25 DEG C. to 150 DEG C.; and hydrolysing the resultant aluminium alcoholate and recovering the alcohol or mixture of alcohols so obtained. An organic inert diluent, e.g. an aromatic hydrocarbon, a C5-C8 paraffin, a halogenated hydrocarbon or an ether, may be present during the reaction.  The aluminium trialkyl used as starting material may be obtained by reacting a C2-C4 aluminium trialkyl with ethylene or by reacting a higher olefine with an aluminium trialkyl having low alkyl groups.

Filed: 1968-09-27
Abstract: 1,274,672. Transistor amplifiers. R.C.A. CORPORATION. 26 Sept., 1969 [27 Sept., 1968], No. 46151/68. Heading H3T. An integrated differential amplifier circuit providing high voltage gain over a wide range of quiescent current levels comprises a longtailed pair 11, 12 (Fig. 1) with a collector load comprising transistors 14-18 interconnected as shown. The output of transistor 16 is inverted at 26 and combined with the output of 17 to provide an amplifier output at 27. The collectoremitter voltages at 14, 15 are substantially constant and equal to the sum of the base emitter voltages across transistors 16 or 17 and 18. Common mode signals, i.e. changes in quiescent current, produced by changing the base bias on transistor 13 will not affect the collector-emitter voltages of transistors 14, 15, and hence will not affect the outputs of transistors 16 and 17. However, for differential signals, transistors 14, 15 present a high impedance since their base drive, determined by the current through 16, 17, 18, is unchanged. Differential signals will therefore be passed to the output 27. In a modification (Fig. 2), transistors 28, 30 have ##10<SP>3</SP> and a collectorbase breakdown voltage of about one volt. Cascade connected transistors 29, 31 biased through base emitter junctions 32, 33 ensure that the collector-base voltages of transistors 28, 30 are zero, thus reducing collector-base leakage current. A transistor 41 provides initial conduction in transistor 18. A pair of transistors (35, 36, Fig. 3, not shown) may be cascodeconnected to transistors (17<SP>11</SP>, 18<SP>11</SP>) in a manner similar to transistors 28, 30, 29, 31, to maintain equal gain in both halves of the amplifier. A further transistor (40) provides initial conduction in the base-emitter junctions controlling the cascode connected transistors (35, 36).

Abstract: 1333283 Refuse compactors INTERNATIONAL POLLUTION CONTROLS CORP 6 Oct 1971 [16 Oct 1970] 46557/71 Heading B8C  An automatic refuse compaction system comprises a refuse-receiving duct 14, a compaction chamber 68 having an open lateral end, a discharge chamber 70 open to the lateral end, compaction means 75-78 movable transversely of the duct to push refuse through the compaction chamber into the discharge chamber, pneumatically operated valve means, pneumatically actuated control means pneumatically connected to the valve means for operating the same and fluid conducting means connecting the valve means in circuit with the compaction means for controlling and operating the same so that the compaction means 75-78 operates cyclically. As shown, refuse fed into a shoot 16 is subjected to a first stage compaction in the compaction chamber 68 by plates 56 which are rotated between vertical and horizontal positions by double-acting pneumatic cylinders 28 whereafter the refuse is pushed by an hydraulically operated ram 72 into the compaction and discharge chamber 70 from which it is discharged by a pneumatically-operated plate 140 through a sliding door 162 operated by pneumatically operated rods 166. Sensing rods 18 in the shoot 16 detect the presence of refuse passing into the shoot, the rods being connected to pneumatic switches 20 controlled by a pneumatically operated control circuit 204, Fig. 5 (not shown), in a housing 25. The apparatus is provided with a fire-extinguishing system comprising a pneumatically operated temperature responsive switch 175 which controls a sprinkler head 186 and which automatically moves the compactor plates to horizontal position to cut off air to any burning material in the chamber 68, and automatically advances the ram 72 to push such material into the chamber 70. Deflection of the rods 18 actuates a spray nozzle of a disinfectant spray unit fed from a tank 190 and a perforated pipe 194 periodically discharges insecticide into duct 16. An hydraulic pressure booster 100, fed from an hydraulic fluid tank 96, automatically boosts the pressure applied to the ram 72 if compaction is resisted by the lower pressure normally used. The apparatus, which is fully automatic in operation, is controlled by a programmed pneumatic circuit, described in detail with reference to Figs. 5 and 6 (not shown). Compressed air for the pneumatic operation is fed from a source remote from the apparatus and several units of the apparatus may be supplied with compressed air from a common source, Fig. 7 (not shown), the control circuit 204 of each unit being connected directly to the air supply for operating the first stage of compaction as required and the second stage of compaction of each unit being connected to a selector (250) programmed to selectively pass air to one unit at a time.
